Module functional characteristics of mobile phone signal jammer

1. Duplex filter

The duplex filter is a necessary module for a high-quality mobile phone signal amplifier (repeater). It is mainly located behind the outdoor antenna and the indoor antenna of the amplifier, which means that the mobile phone signal is always received or transmitted. Filters are required to better isolate and filter out clutter signals. The filters of radio frequency equipment are generally composed of cavities, and the filtering performance is good for out-of-band suppression. Adjacent waveguide suppression and spurious wave radiation are both very good. important. A single radio frequency filter cannot guarantee the effect of the call. Using an intermediate frequency filter method and using a surface filter method, and adding a corresponding circuit can effectively improve the stability of the filter.

2. Low noise jammer

In the mobile phone signal jammer, the uplink and downlink signals must be amplified by a low-noise amplifier, which has a good weak signal amplifier capability.

3. Power jammer

The high power jammer is an important part of the mobile phone signal amplifier. The main function of the power amplifier is to transfer the base station that needs to be forwarded.

4. Monitoring unit

Under normal circumstances, the circuit of the mobile phone signal amplifier for civilian use can be removed. The monitoring unit is to timely summarize the problems of the equipment and the situation of the mobile phone signal amplifier to the network management center. The monitoring unit can detect the working conditions and parameters of the internal components of the mobile phone signal amplifier. Change the situation and set the main parameters.

5. Power

The power supply is the working energy of the mobile phone signal amplifier. It can be powered by a battery to ensure the normal operation of the mobile phone signal amplifier when the power is off. Solar or wind power can be used in relatively remote mountainous areas.
